What would an extrasolar observer see of our solar system?  We find out in this month's Naked Astronomy as well as explore the events that led to climate change on a cosmic scale.  Plus, news of an asteroid flyby, surfing Venus' atmosphere and the end of the WMAP.  We take on your space science questions, including the best place to site a space elevator!
